## Discrepancy

(CAN) PILOTS REPORTED FLAP SYSTEM 1 AMP CIRCUIT BREAKER ON BATTERY BUS TRIPPED WHEN FLAP SELECTED DOWN. THE SYSTEM WOULD FUNCTION NORMAL IF THEY KEPT THE AIR SPEED BELOW 140 KNOTS. THE FAILURE COULD NOT BE DUPLICATED ON THE GROUND. THE FLAP POWER DRIVE UNIT WAS REPLACED. THE AIRCRAFT WAS FLOWN AND FLAPS EXTENDED AT MAX EXTENSION SPEED AND SYSTEM FUNTIONED NORMAL.
